To all whom t may concern:

Be it known that I, JULiUs F. Gon'rz, a citizen of the United States,and resident of Hartford, in the county of `Washington and State ofWisconsin, have invented new and useful Improvements in Vaporizer andAir- Supply Devices, of which the following is a description, referencebeing had tothe y'accompanying drawings which are a part of thisspecification.

This invention relates to improvements in vaporizer and air supplydevices.

In internal combustion engines more par ticularly adapted for automobileuse, it has been found that the engines run to better advantage undersome atmospheric conditions than others and that this result is produced more or less by the varying conditions of humidity of the air.Many attempts have been made to provide means for meeting the differentatmospheric changes, but kheretofore the means do not permit theconvenient control of the devices.

It is one of the objects of the lpresent invention to provide a combinedvaporizer and air supply device which will supply vapor and hot or coldair to thecarbureter of the engine as required to supply the propermixture under any atmospheric condition.

A further object of the invention vis to provide a vaporizer and airsupply device in which the controls of the vapor and hot and cold airare combined in a manner to be conveniently operated from the dash orother point desired of the automobile.

A further obj ect of the invention is to provide a vaporizer and airsupply device which may be connected to the valve of the carbureter tocontrol the combined flow of vapor and air thereto.

A further object of the invention is to provide a vaporizer and aircontrol device which may be easily connected to a carbureter of anordinary engine in a manner to efliciently mix the vapor and air withthe carbureter explosive fluid.

A further object of the invention is to provide a vaporizer and hot andcold air supply device in which any desired combustible 'iiuid mixturemay be obtained to suit vdiiferent atmospheric conditions.

A further object of the invention is to provide a vaporizer and airsupply device VInthe accompanying drawings in which the same'referencecharacters indicate the same' parts in all of the views:

vof lthe 10 is a vertical sectional detail view, i

on a larger scale, of theA part sho-wn in Fig. 9. y Referring to thedrawings, the numeral 12 indicates aninternal combustion engine, 1.3

the carbureter, 14 the radiator and 15 a porf y tion of ther dash andrinstrument boardr of anV automobile. The improved` vapori'zer and airsupply ydevice is connected to ythe parts 'mentioned yand ycomprisesmainlyy the plural valve 16, the controllingmain valve 17 and the pluralvalve controllers 18.-A

The plural valve y1'6y consists of a valve member 19 having four conicalplug valves 20, 21, 22 and 23 mountedl therein and rotatable to havetheir respective portsE intersect ,y

and register with ports 24,25, 26 and 27 ,f

, ed to preferably flexible steel wire or rods 29 which extend forwardlyand at their forwardends are-clamped in the inner ends of controllingmembers or handles 30 which are journaled in a controller plate 31. Thecontrolling members are formed with indicating pointed portions 30 andthe controller v platel is provided. with indicating segmental scales 32to indicate the adjustment of the opening of each valve. Coiled springs33 surrounding the controlling members or handles and interposed betweenportions of the controller plates and portions of the controllingmembersmaintain said controlling -members in adj usted position.

. The ycontroller plate 31 is preferably mounted on the instrument boardof an automobile and as the controlling handles carried by said platelare preferably in horizontal alinement with each other and out ofalinement with the plug valves with which they are respectivelyconnected, the steel rod connections 29 provide the necessaryflexibility to permit the easy turning of the plug valves.

A tube 34 coupled to the hot air port portion 24 of the valveI member 19extends to a position adjacent the exhaust pipe 35 and isconnected to atubular heater member-36 whichr partly surrounds and is spaced from theexhaust pipe. The air in the space between the heater member and theexhaust pipe is heated by the exhaust pipe and is drawn through the tube34 to the valve mixing chamber 28.

A tube 37 coupled to the vapor port portionv25 of the valve member 19extends to ,the radiator 14 of the automobile and is provdedwith anextension 37 `which extendsinto the upper portion of the radiator and iscurved upwardly and its upper end terminates at a point in the upperportion 38 of the filling opening of said radiator. Openings 39 formedin said upper pipe end permit the moist vapor in the upper portion oftheradiator to enter the tube and be drawn to the mixing chamber 28r of thevalve member 16.

The cold air port portion 26 of the valve member 16 is also providedwith a coupled tube 40 which extends to any convenient point andfisfastened to the dash board by a securing member 41. The terminating endof this ltube isprovided with a screen cover 42 which prevents dust orother foreign matter being drawn into the tube and the valve mixingchamber 28, with the cold air.

A tube 43 connected to the outlet port port-ionf27 extends and isconnected to the carbureter 13 by an annular member 44 which isinterposed between thc carbureter and the engine. The annular member isshaped to correspond to the shape of the carbureter connecting flange topermit the same bolts 45 to connect the parts together.

The annular member 44 is formed with an annular space or chamber 44:lhaving an inner wall of perforated or screen'material 46 to efficientlymix thev vapor or hot or cold air with the combustible mixture passingthrough the annular member Afrom the Vcarbureter to the engine. A screenor perforated disk 47 may also be used if desired to more completelyatomize the particles of gasoline orother fluid which might be carriedby the air. 7

The yshut offv valve 17 before mentioned is connected in circuit with orintersects the flow of air orvapor through the tube 43 and thecontrolling plug member 17 of this valve has a yielding connection 48with the throttle valve49 of the carbureter 13 so that when saidthrottlevalve is controlled in the ordinary way from the steering head'thesupply of vapor or hot or cold air from the device will be automaticallycontrolled independently of the proportionate controls of the vapor orhot and cold air. i

In the modified form shown in F ig. 9 the tube 43- is connecteddirectlyto carbureter and is provided with a perforated and screened extension50 which extends into the carbureter in the path of travel 'of thecombustible mixture and supplies` the hot or cold air or vapor thereto.v

From the foregoing description, it will be seen that varying amounts ofvapor or hot or cold air may be easily mixed and controlled and suppliedto the combustible fluid fed to the engine to suit varying atmosphericconditions and thereby provide an efficient mixture at all times. f

What I claim as my invention is:

1. The combination with an engine havingl a carbureter, a radiator andan. air heater, of a valve structure comprising a mixing chamberprovided with two inlet ports and an outlet port, pipes connecting saidinlet port-s with the radiator and the air heater, respectively, a pipeconnecting said outlet port with the carbureter, a valve in said lastmentioned pipe, Ameans operatively connecting said valve withthethrottlevalve of the carbureter, valves controlling said inlet ports,and means operable from a remote point fork controlling independentlysaid last mentioned valves, whereby the relative proportions of air andvapor admitted tol said mixing chamber may be varied .at

will and the mixture delivered to the oarbureter controlledsimultaneously with the movement of the carbureter throttle valve'.

2. The combination with an engine having a carbureter, a radiator and anair heater, of a valve structure comprising a mixing chamber providedwith three inlet ports and an outlet port, pipes connecting said inletports With the radiator, air heater and a source of Cold air supply,respectively, a pipe connecting said outlet port with the earbureter, avalve in said last mentioned pipe, means'o eratively connecting saidvalve with t e throttle valve of the carbureter, valves controlling saidinlet ports7 and means operable from a remote point for controllingindependently said last mentioned valves, Whereby the relativeproportions of Warm air, oold air and vapor admitted to said mixingchamber may be varied at will and the mixture delivered to thecarbureter controlled simultaneously With the movement of theearhur'eter throttle valve.

In testimony whereof, I ahx my signature.
